See what a dollar amount from any year is worth today, or what today's dollars were worth in the past.
This calculator uses the Consumer Price Index (CPI) published by the U.S. Bureau of Labor Statistics. The CPI measures the average change in prices paid by urban consumers for a basket of goods and services. To convert an amount from one year to another, we multiply by the ratio of the CPI values.
For example, $100 in 2000 had a CPI of about 172.2, while the 2025 CPI is approximately 319.1. So $100 in 2000 equals roughly $100 x (319.1 / 172.2) = $185.31 in 2025 dollars.
Inflation erodes purchasing power over time. If your salary rises 2% per year but inflation averages 3%, you are effectively earning less each year. Understanding inflation is critical for retirement planning, salary negotiations, investment returns, and evaluating historical prices.
U.S. inflation has averaged about 3.2% annually since 1913. The highest year was 1917 at 17.8%, and the most notable modern spike was 2022 at 8.0%. Deflation (negative inflation) occurred during the Great Depression (1930-1933) and briefly in 2009.
